Yes, there are test kits for many parameters. However, they are probably not going to be as comprehensive or accurate as having a suite of tests performed by a reputable lab such as Ward. The most economical of the test kits are those used by home aquarium hobbyists.
In my opinion, you are better off with the Ward test if your well water quality is typically constant (most are). If you have a variable water quality, then having at least an alkalinity and calcium test kit will help you to assess the most important parameters to brewing.
